Dowel Pins


Dowel pins are often used as precise locating devices in machinery.  Steel dowel pins are machined to tight tolerances, as are the corresponding holes. When designing mechanical components, mechanical engineers typically use dowel holes as reference points to control positioning variations. If something other than a dowel pin is used for alignment, there can be significant variation in component positioning. Dowel pins can also be used as locators so that a part can be removed and will retain its accurate location when replaced.

With a product like dowel pins, a diverse selection is necessary. Our expert staff is ready to meet a wide range of customer needs. Some applications are more demanding than others, requiring dowel pins that may be difficult to find elsewhere. With our expansive inventory and custom capabilities, PIC can keep you on target by helping you find the right product for your job.
